Perinatal Anxiety Screening Scale validiy and reliability study in Turkish (PASS-TR validity and reliability)

Perinatal anxiety disorders screening study: a study protocol

BACKGROUND

The anxiety and their related disorders (AD) are the most common of all mental health conditions, and affect approximately 20% of pregnant and postpartum people. They are associated with significant distress and life interference for sufferers, as well as negative consequences for fetal and infant development. At present, little if any routine screening for prenatal AD is being conducted and data regarding the most effective tools to screen for these disorders is lacking. The majority of screening studies suffer from methodological difficulties which undermine the confidence needed to recommend measures for population distribution. The primary purpose of this research is to identify the most accurate self-report tool(s) to screen for perinatal AD.

METHODS

A large, prospective cohort of pregnant people (N = 1,000) is being recruited proportionally across health service delivery regions in British Columbia (BC). The screening accuracy of a broad range of perinatal AD self-report measures are being assessed using gold standard methodology. Consenting individuals are administered online questionnaires followed by a semi-structured diagnostic interview between 16- and 36-weeks' gestation, and again between 6 and 20 weeks postpartum. Questionnaires include all screening measures, measures of sleep and unpaid family work, and questions pertaining to demographic and reproductive history, COVID-19, gender role burden, and mental health treatment utilization. Interviews assess all current anxiety disorders, as well as obsessive-compulsive disorder, and posttraumatic stress disorder.

DISCUSSION

This research is in response to an urgent demand for accurate perinatal AD screening tools based on high quality evidence. AD among perinatal people often go unidentified and untreated, resulting in continued suffering and life impairment. Findings from this research will inform healthcare providers, policymakers, and scientists, about the most effective approach to screening for anxiety and related disorders in pregnancy in the postpartum period.

The effect of prenatal anxiety on prenatal attachment in high-risk pregnant women and related factors: a cross-sectional study

High-risk pregnant women experience stress and anxiety. Anxiety may affect prenatal attachment. This study aimed to examine the effect of anxiety on prenatal attachment in high-risk pregnant women. The study was cross-sectional and conducted on 290 high-risk pregnant women who applied to the perinatology outpatient clinic of a university hospital between February and July 2022. The data were collected with the descriptive information sheet, Prenatal Attachment Inventory (PAI), and Perinatal Anxiety Screening Scale (PASS). Mann-Whitney U, Kruskal Wallis-H, and Spearman's Correlation tests were used to analyze the data. The mean age of the examined pregnant women was 28.12 ± 5.36, and most of them were multigravida (65.5 percent) and in the third trimester (80.7 percent). The PAI and PASS mean scores were 64.09 ± 11.31 and 27.98 ± 16.52, respectively. There was a weak positive correlation between anxiety and prenatal attachment (r = .227, p < .001). The levels of prenatal attachment were higher in primigravidas and women with no children. Also, the anxiety levels of pregnant women in the third trimester were lower. Health professionals should evaluate the prenatal attachment and anxiety levels of high-risk pregnant women, and consider obstetrical factors that may influence both prenatal attachment and anxiety levels.

Being a Mother under the COVID-19 Pandemic Lockdown: Evaluation of Perinatal Anxiety, Prenatal Attachment, and Maternal-Infant Attachment

OBJECTIVES

The novel coronavirus disease 2019 (COVID-19) pandemic has caused both physical and emotional stress throughout the population due to its worldwide impact. The unknowns about the disease, social isolation, pregnant women's concerns regarding exposure to the COVID-19, inaccessibility to necessary care, and the possibility of harm to their fetus may cause increased psychological distress during the perinatal period. We aimed to evaluate the association between perinatal anxiety, prenatal attachment, and maternal-infant attachment status among women with those who delivered their child in a tertiary-care center with rigid hospital restrictions.

STUDY DESIGN

Term pregnant women who experienced the last trimester of their pregnancy during COVID-19 curfews between December 2020 and May 2021 were asked specifically about their concerns during the COVID-19 pandemic and they filled out the Perinatal Anxiety Screening Scale (PASS) and the Prenatal Attachment Inventory (PAI). Those who continued the follow-up within a month of period following the delivery were invited to fill out the Maternal Attachment Inventory (MAI).

RESULTS

A total of 600 women completed the survey. While the evaluation of the relationship between participants' mean PAI and MAI scores showed a statistically significant positive correlation between scales (r = 0.124, p = 0.002), mean PAI and PASS scores showed a statistically significant negative correlation between scale scores (r = - 0.137, p = 0.001).

CONCLUSION

Examining the factors, affecting the attachment process of pregnant and puerperal women, will guide the improvement of the quality of health services in the COVID-19 pandemic.

KEY POINTS

· COVID-19 caused psychological distress, with increased anxiety among perinatal women.. · Elevated levels of anxiety about COVID-19 during pregnancy may lead to insecure attachment.. · Insecure attachment in the prenatal period will negatively contribute to mother - infant attachment..

Detection of depression and anxiety in the perinatal period using Marine Predators Algorithm and kNN

Undiagnosed prenatal anxiety and depression have the potential to worsen and have an adverse effect on both the mother and the infant. Although the diagnosis is made by specialist doctors, it is unclear which parameters are more effective. Especially in medicine, it is crucial to diagnose disease with high accuracy. For this reason, in this study, a questionnaire study was first conducted on pregnant women, and real original data were collected. Then, the Marine Predators Algorithm (MPA), one of the current metaheuristic algorithms inspired by nature, was combined with K-Nearest Neighbors (kNN) to determine high-priority features in the collected data. As a result, five of the 147 features selected by the proposed method were determined as high priority and approved by the doctors. In addition, the proposed method is compared with the Chi-square method, which is one of the filter-based feature selection methods. Thanks to the proposed feature selection method based on MPA and kNN, it has been observed that the classification gives more successful results in a shorter time with 98.11% success, and the model supports the diagnosis stage of the doctors.

Validation of the Persian version of the Perinatal Anxiety Screening Scale (PASS) among antenatal and postnatal women

BACKGROUND

Anxiety disorder is more common in women than men. To some extent, it can be attributed to childbirth and factors related to pregnancy in women. Therefore, it is necessary for mothers to use valid and reliable scale to assess perinatal anxiety, such as the perinatal anxiety screening scale (PASS). The purpose of this study was to investigate the validity and reliability of the PASS in Persian language.

METHODS

The PASS was translated into Persian (PASS-IR). Generally, 224 women antenatal and 125 postnatal answered the questions of PASS, EPDS-10, BAI and DASS-21 questionnaires. The data was collected in the health centers of Kerman by random sampling method. Finally, content validity, factor analysis, internal consistency and test-retest reliability were evaluated.

RESULTS

The mean age of the participants was 32.89 years (range between 18 and 45 and SD = 6.23). More than half of the participating were at risk of severe anxiety (53.5%). Content Validity Index (CVI) and Content Validity Ratio (CVR) were 0.80 and 0.87. PASS-IR subscales include social anxiety and specific fears, general anxiety and adjustment, acute anxiety and trauma, and perfectionism and control. PASS-IR was significantly correlated with EPDS-10 (rho = 0.42), BAI (rho = 0.53), DASS-21 with three concepts of depression, anxiety and stress (rho = 0.51, rho = 0.49 and rho = 0.49), and adverse life events (rho = 0.30).

CONCLUSION

The results of this study show that PASS-IR has good validity and reliability. Therefore, it can be used to screen for anxiety disorder among Iranian women in the perinatal stage.

Examining the relationship between perinatal anxiety, COVID-19 phobia and birth type preferences: A cross-sectional study

AIM

To examine the relationship between the COVID-19 phobia and perinatal anxiety levels and birth type preferences of pregnant women in the third trimester.

DESIGN

This was designed a cross-sectional study using the non-random convenience sampling method following the STROBE checklist.

METHODS

The research was conducted with 315 pregnant women from April to May 2021. Data were collected using a personal information form, the COVID-19 Phobia Scale, and the Perinatal Anxiety Screening Scale (PASS).

RESULTS

We found a positive and moderate correlation between the total scores for perinatal anxiety and COVID-19 phobia. During the COVID-19 pandemic, 4.1% of the participants changed their birth type preferences and this change was statistically significant according to McNemar's test. During the COVID-19 pandemic, the women changed their birth type preferences in favour of caesarean section. However, there was no statistically significant difference between those who changed their birth type preferences and those who did not in terms of perinatal anxiety or COVID-19 phobia levels. Women with no access to prenatal follow-up visits due to the COVID-19 pandemic had higher mean PASS scores and higher mean scores for the perfectionism, control and trauma subscale. The scores for general worry and specific fears were lower among individuals who had obtained information about birth types in prenatal follow-up visits. Also, perinatal anxiety and COVID-19 phobia levels were higher among pregnant women who were worried about giving birth in hospital compared to those who were not worried.

CONCLUSION

We conclude that COVID-19 phobia has increased women's perinatal anxiety, causing them to change their birth type preferences in favour of caesarean section.

RELEVANCE TO CLINICAL PRACTICE

We recommended that healthcare professionals take COVID-19 phobia and perinatal anxiety into account when counselling pregnant women about birth types to improve prenatal care.

NO PATIENT OR PUBLIC CONTRIBUTION

No patient or public contribution was required to design, to outcome measures or undertake this research. Patients/members of the public contributed only to the data collection. Data were obtained from pregnant women in the third trimester, who came to a regional hospital-affiliated obstetrics polyclinic for routine prenatal follow-up visits.

Screening for anxiety disorders in third trimester pregnancy: a comparison of four brief measures

Evidence regarding the accuracy of existing anxiety screeners used in pregnancy is limited. This study compares the psychometric characteristics of the Generalized Anxiety Disorder 2- and 7-item Scales (GAD-2 and GAD-7), the anxiety subscale of the Edinburgh Postnatal Depression Scale (EPDS-3A) and the two anxiety items of the Antenatal Risk Questionnaire (ANRQ-2A). Nine hundred fifty-four women completed the screening measures and anxiety modules of a diagnostic reference standard (SAGE-SR) in the third trimester. Test performance characteristics of each measure was assessed using Receiver Operator Characteristic (ROC) analysis. We applied four previously recommended criteria to ascertain the value of each measure for widespread clinical use: area under the curve (AUC ≥ 0.8, Youden's index ≥ 0.5, negative predictive value (NPV) ≥ 0.8 and positive likelihood ratio (LR +) ≥ 4.0). Prevalence for any SAGE-SR anxiety disorder was 3%. All measures yielded an acceptable AUC of ≥ 0.8, Youden's index of ≥ 0.5 and NPV of ≥ 0.8. Only the EPDS-3A, at a cut-point ≥ 5, also achieved a LR + of ≥ 4.0 (4.35) but at this cut-point sensitivity was less than 0.75. The ANRQ-2A, at its optimal cut-point of ≥ 6, was the only measure to additionally attain both a sensitivity and specificity of ≥ .75. This study expands the evidence base for brief anxiety screening measures in the maternity setting and provides empirical support for the use of the EPDS-3A and ANRQ-2A in routine screening programmes. Studies assessing the performance of these measures in samples with higher disease prevalence and broader socio-economic status are warranted.

Mothers' Experiences of Pregnancy, Labor and Birth, and Postpartum During COVID-19 in the United States: Preliminary Results of a Mixed-Methods Study

The purpose of this study was to gain insight into the experiences of women who gave birth in the United States during coronavirus disease-2019 (COVID-19). A mixed-methods study was performed using online surveys and interviews. Data were analyzed using descriptive statistics and interview transcripts were analyzed by thematic analysis resulting in major themes. Participants (n = 32) were women who had given birth on or after March 13, 2020. Of the participants, 34% experienced depression, 46% experienced mild to moderate anxiety, and 28% experienced severe anxiety symptoms. Four major themes emerged: expectations versus reality, early versus late COVID-19 experience, mental distress versus mental health, and healthcare policy versus COVID-19 confusion. Experiences varied based upon geographical location, parity, and proximity to support. Short and long-term effects of COVID-19 on participants and their families were recognized. It is important to acknowledge the confusion experienced in many aspects of the birthing experience due to developing or conflicting pandemic or popular media information. Aligning expectations through providing clear, up-to-date information is helpful in decreasing mental distress. Finally, the impact of COVID-19 highlighted the critical need for professional and focused familial support and follow-up for women experiencing pregnancy-related mental health symptoms.

Psychometric Properties of the Perinatal Anxiety Screening Scale Administered to Italian Women in the Perinatal Period

Literature stressed the importance of using valid, reliable measures to assess anxiety in the perinatal period, like the self-rated Perinatal Anxiety Screening Scale (PASS). We aimed to examine the psychometric properties of the Italian PASS version in a sample of Italian women undergoing mental health screening during their third trimester of pregnancy and its diagnostic accuracy in a control perinatal sample of psychiatric outpatients. Sample comprised 289 women aged 33.17 ± 5.08, range 19-46 years, undergoing fetal monitoring during their third trimester of pregnancy, with 49 of them retested 6 months postpartum. Controls were 60 antenatal or postnatal psychiatric outpatients aged 35.71 ± 5.02, range 22-50 years. Groups were assessed through identical self- and clinician-rating scales. Confirmatory Factor Analysis (CFA), Principal Component Analysis (PCA), Pearson's correlations and receiver operating characteristic were conducted for PASS. PCA and CPA confirmed four-factor structure with slight differences from the original version. Construct validity and test-retest reliability were supported. Cut-off was 26. The PASS correlated with principal anxiety scales. Despite small sample size, findings confirm reliability and validity of the Italian PASS version in assessing anxiety symptoms in the perinatal period. Its incorporation in perinatal care will improve future mother and child psychological health.

The Effect of Showing Images of the Foetus with the Virtual Reality Glass During Labour Process on Labour Pain, Birth Perception and Anxiety

AIM AND OBJECTIVES

This study was conducted to determine the effect of showing images of the foetus to the pregnant women with the virtual reality glass during labour process on labour pain, childbirth perception and anxiety level.

BACKGROUND

Virtual reality is an effective and inexpensive method that allows the creation of simulated scenarios in which it interacts with the virtual environment with multisensory stimuli.

DESIGN

This is a randomised controlled experimental study. This study was conducted with the guidelines of Consolidated Standards of Reporting Trials (CONSORT). The study was enrolled in the Clinical Trials database (NCT04664114).

METHODS

The study included 100 pregnant women (50 intervention group and 50 control group). Ultrasound images of the foetus were recorded on the 28th week of pregnancy of the women in the intervention group. These images were shown to the women with the virtual reality glass during labour process. Routine procedures were carried out for the women in the control group. The Visual Analog Scale (VAS) was applied to both groups when cervical dilatation was 4 cm and 9 cm. The Women's Perception for the Scale of Supportive Care Given During Labor (POBS) and the Perinatal Anxiety Screening Scale (PASS) were applied almost two hours after labour.

RESULTS

The VAS scores of the women in the intervention group with 9 cm dilatation and their PASS mean scores were significantly lower than women in the control group while their POBS score were significantly higher (p < 0.01).

CONCLUSION

The results of this study show that showing images of the foetus to women with virtual reality decreased labour pain and anxiety level.

RELEVANCE TO CLINICAL PRACTICE

It is known that supportive care given during labour is important both for the mother's and baby's health. Therefore, it is important that nurses and midwives, who spend the most time with women and provide the most support, reduce the pain and anxiety of the woman with nonpharmacological practices and make them feel positive feelings about delivery.

Validation of the Arabic version of the Perinatal Anxiety Screening Scale (PASS) among antenatal and postnatal women

BACKGROUND

Anxiety among women in the perinatal period is common. Assessing the severity of perinatal anxiety will help monitor the progress of the patient through the stages of anxiety and facilitated the treatment. This study assesses the validity and reliability of the "Perinatal Anxiety Screening Scale" (PASS) in the Arabic language.

METHODS

The PASS was translated into Arabic. Two hundred seventeen women in the antenatal and postnatal phase participated (92 antenatal and 125 postnatal) answered to PASS, GHQ12, EPDS-10, and DASS-21. Content validity, factor analysis, internal consistency, and test retest reliability were assessed.

RESULTS

Content Validity Index (CVI) and Content Validity Ratio (CVR) were .88 and 0.79; respectively. The scale loaded on four components: acute anxiety, social anxiety, and dissociation; specific fears and trauma; general anxiety and adjustment; and perfectionism and control. Cronbach's Alpha value for the scale was 0.78 and test retest correlation coefficient was 0.94. PASS significantly correlated with EPDS-10 (rho=0.46), GHQ-12(rho=0.58), the three components of DASS-21 (0.47, 0.50, and 0.43; respectively), and experiencing adverse life events.

CONCLUSION

The Arabic translated version of the PASS showed reasonably adequate validity and reliability and can be used to screen for anxiety disorder among women in the perinatal phase.

Trajectories and predictors of anxiety symptoms during pregnancy in an Australian sample

BACKGROUND

There is a growing realisation that anxiety symptoms and disorders during pregnancy are associated with various negative outcomes. The aims of this study were to identify latent classes of anxiety symptom trajectories during pregnancy, compare anxiety levels between pregnancy trimesters and ascertain the predictors of anxiety symptom trajectories.

METHODS

Two hundred pregnant women in their first trimester who attended obstetric clinics at the local hospital were recruited. Three self-report questionnaires assessing anxiety levels were administered at three time points during pregnancy. Latent class growth analysis was used to identify anxiety symptom trajectories, and logistic regression analysis was performed to ascertain the predictors of latent class membership.

RESULTS

Data for analyses were available for 188 women. Two anxiety symptom trajectories were identified: a 'high-anxiety' trajectory (13.3% of participating women) and 'low-anxiety' trajectory (86.7%). This finding was consistent across all the anxiety measures used in the study. Overall, anxiety levels gradually decreased during pregnancy, with a significant decrease between the first and second trimesters on some measures. Past mental disorders and significant stressors in the preceding 6 months predicted membership in the 'high-anxiety' trajectory group.

CONCLUSIONS

These findings support an early assessment of anxiety in pregnant women. If untreated, a high level of anxiety in the first trimester is likely to persist throughout pregnancy, although it may decrease somewhat. An early recognition of pathological anxiety during pregnancy allows its timely treatment and prevention of unfavourable outcomes.

Sinhala translation of the Perinatal Anxiety Screening Scale: a valid and reliable tool to detect anxiety disorders among antenatal women

BACKGROUND

Anxiety disorders during pregnancy are not routinely assessed in Sri Lanka despite being common and being associated with adverse pregnancy outcomes. Screening can facilitate early detection and management of anxiety and improve pregnancy outcomes. Our aim was to determine the validity of the Sinhala translation of the Perinatal Anxiety Screening Scale (PASS) to detect anxiety among Sri Lankan pregnant women.

METHODS

A cross-sectional study was conducted in antenatal clinics of a teaching hospital in Colombo District. The PASS was translated to Sinhala using the standard translation/ back-translation method. Pregnant women (n = 221) were sequentially recruited and assessed by a psychiatrist until 81 women with anxiety disorder were diagnosed using the International Classification of Diseases-10 criteria (gold standard). The Sinhala translation of the PASS (PASS-S) was administered to all recruited women, including 140 women without anxiety. Receiver-Operating- Characteristic (ROC) analysis was performed, the optimal cut-off score for PASS-S was determined, and its validity was assessed using sensitivity, specificity, predictive values and positive and negative likelihood ratios. Internal consistency was assessed using Cronbach's alpha. Test-retest and inter-rater reliability for PASS-S score and anxiety classification were assessed using intra class correlation coefficient (ICC) and Cohen's kappa (k), respectively.

RESULTS

The mean age (±SD) of women was 30(±5.8) years, and 53.7% were multiparous. A psychiatrist diagnosed anxiety disorder was made in 37.0% of women, while the PASS-S, at its optimal cut-off of ≥20, classified 37.5% of women as having anxiety disorders. The area under the ROC curve for the PASS-S was 0.96 (95%CI 0.94-0.99). Sensitivity, specificity and positive and negative predictive values of the PASS-S were 0.93 (95% CI 0.84-0.97), 0.90 (95% CI 0.83-0.94), 0.85 (95% CI 0.75-0.90) and 0.95 (95% CI 0.89-0.98), respectively. Positive and negative likelihood ratios were 8.8 (95% CI 5.3-14.5) and 0.08 (95%CI 0.04-0.18), respectively, and the internal consistency was high (Cronbach's alpha 0.95). Four-factor structures obtained by exploratory factor analysis were "acute anxiety and adjustment", "social anxiety, specific fears and trauma", "perfectionism and control" and "general anxiety".Test-retest reliability was high for the PASS-S score (ICC 0.85[95% CI 0.65-0.96]) and anxiety classification (k 0.77[95% CI 0.34-1.2]). Inter-interviewer reliability was also high (ICC 0.92[95% CI 0.81-0.97] for the PASS-S score and (k0.86 [95% CI 0.59-1.1] for anxiety classification).

CONCLUSION

The Sinhala translation of the PASS is a valid and reliable instrument to screen for anxiety disorders among antenatal women in Sri Lanka.

A systematic review of validated screening tools for anxiety disorders and PTSD in low to middle income countries

BACKGROUND

Anxiety and post-traumatic stress disorder (PTSD) contribute significantly to disability adjusted life years in low- to middle-income countries (LMICs). Screening has been proposed to improve identification and management of these disorders, but little is known about the validity of screening tools for these disorders. We conducted a systematic review of validated screening tools for detecting anxiety and PTSD in LMICs.

METHODS

MEDLINE, EMBASE, Global Health and PsychINFO were searched (inception-April 22, 2020). Eligible studies (1) screened for anxiety disorders and/or PTSD; (2) reported sensitivity and specificity for a given cut-off value; (3) were conducted in LMICs; and (4) compared screening results to diagnostic classifications based on a reference standard. Screening tool, cut-off, disorder, region, country, and clinical population were extracted for each study, and we assessed study quality. Accuracy results were organized based on screening tool, cut-off, and specific disorder. Accuracy estimates for the same cut-off for the same screening tool and disorder were combined via meta-analysis.

RESULTS

Of 6322 unique citations identified, 58 articles including 77 screening tools were included. There were 46, 19 and 12 validations for anxiety, PTSD, and combined depression and anxiety, respectively. Continentally, Asia had the most validations (35). Regionally, South Asia (11) had the most validations, followed by South Africa (10) and West Asia (9). The Kessler-10 (7) and the Generalized Anxiety Disorder-7 item scale (GAD-7) (6) were the most commonly validated tools for anxiety disorders, while the Harvard Trauma Questionnaire (3) and Posttraumatic Diagnostic Scale (3) were the most commonly validated tools for PTSD. Most studies (29) had the lowest quality rating (unblinded). Due to incomplete reporting, we could meta-analyze results from only two studies, which involved the GAD-7 (cut-off ≥10, pooled sensitivity = 76%, pooled specificity = 64%).

CONCLUSION

Use of brief screening instruments can bring much needed attention and research opportunities to various at-risk LMIC populations. However, many have been validated in inadequately designed studies, precluding any general recommendation for specific tools in LMICs. Locally validated screening tools for anxiety and PTSD need further evaluation in well-designed studies to assess whether they can improve the detection and management of these common disorders.
